Data collected by the D0 detector at a pp¯ center-of-mass energy of 1.96 TeV at the Fermilab Tevatron Collider have been used to search for pair production of the lightest supersymmetric partner of the top quark decaying into bℓν˜ . The search is performed in the ℓℓ′=eμ and μμ final states. No evidence for this process has been found in data samples of approximately 400 pb −1 . The domain in the [ M(t˜1),M(ν˜) ] plane excluded at the 95% C.L. is substantially extended by this search.
